A recent AWS CloudFormation stack update has failed and returned the error UPDATE_ROLLBACK_FAILED. A SysOps Administrator is tasked with returning the CloudFormation stack to its previous working state. What must be done to accomplish this?
A.
Fix the error that caused the rollback to fail, then select the Continue Update Rollback action in the console.
B.
Select the Update Stack action with a working template in the console.
C.
Update the password of the IAM user, then select the Continue Update Rollback action in the console.
D.
Use the AWS CLI to manually change the stack status to UPDATE_COMPLETE, then continue updating the stack with a working template.
When a CloudFormation stack update fails and returns the error UPDATE_ROLLBACK_FAILED, it means that the rollback to the previous working state was not successful. The stack update could have failed due to a variety of reasons, such as issues with resource creation, deletion, or updates.
To return the CloudFormation stack to its previous working state, the SysOps Administrator should first identify and fix the error that caused the rollback to fail. The error must be resolved to ensure the stack is in a stable state.
A.
To continue rolling back an update (AWS CLI)
Use the aws cloudformation continue-update-rollback command with the stack-name option to specify the ID of the stack that you want to continue to roll back.
